ABSTRACT
Congenital cutis laxa is a rare, clinically and genetically heterogeneous group of inherited disorders. It is characterized by degenerative changes in elastic fibres and manifests with skin laxity. Here we presented a six-month old boy with congenital cutis laxa associated with growth retardation. We reveal ultrastructural findings and discussed the differential diagnosis.
El laxa del cutis es un grupo raro, clínica y genéticamente heterogéneo de desórdenes heredados. Esta afección se caracteriza por cambios degenerativos en las fibras elásticas y se manifiesta en la hiperlaxitud de la piel. Aquí presentamos el caso de un niño de seis meses con cutis laxa congénita asociada con retardo del crecimiento. Se revelan los hallazgos ultra-estructurales y se discute el diagnóstico diferencial.

In this study, the removal of color, chemical oxygen demand (COD) and aromatic group from one of the azo dyes, Remazol Yellow RR Gran, had been carried out by using one of the white rot fungi, Phanerochaete chrysosporium. Experimental studies were performed in growth media containing different amounts of dye and glucose. Color measurements were done at 436nm wavelength using spectrophotometer while aromatic group measurements were done at 280 nm wavelength using UV/Visible spectrophotometer. As a result of this study the values of the removable color concentration were determined as 10 mgl(-1) and lower. The optimum medium glucose concentration was determined to be 2 gl(-1) during color removal processes, aromatic group measurements were done in samples in the UV region at 280 nm wavelength. As a result of the measurements, it was shown that certain amount of aromatic group remained in the model wastewater at the end of the process.

Transcutaneous Doppler ultrasound measurements were made of the superior mesenteric artery of 25 term infants to correlate the intestinal blood flow with neonatal acid-base status as measured in umbilical artery blood and newborn condition as reflected by Apgar score. Compared with the babies whose umbilical artery pH was higher than 7.20 (peak systolic velocity: 84.1 cn/sn, mean velocity 48.6 cm/sn), the blood flow of superior mesenteric artery was significantly decreased in the newborn babies whose umbilical artery pH was less than 7.20 (peak systolic velocity 48.8 cm/sn, mean velocity = 32.6 cm/sn). Although no such relationship existed between Apgar scores and superior mesenteric artery blood flow indices, a significant linear correlation between superior mesenteric artery blood flow and umbilical artery pH was noted. A reduction of intestinal circulation was observed during umbilical cord blood acidemia and hypoxemia.
